Kinematic properties of reaching movements reflect constraints imposed on the joint angles. Contemporary models present solutions to the redundancy problem by a pseudoinverse procedure (Whitney 1969) or without any inversion (Berkenblit et al. 1986). Feldman & Levin suggest a procedure based on a regular inversion. These procedures are considered as an outcome of a more general approach.

In Schmidt's experiments, only properties of actually produced movements systems are measured; in Fitts' experiments, external task parameters are measured too (target size and distance). Thus, the laws contain variables of different natures and cannot be reduced to each other even formally. These difference especially reveals itself in modeling: a model of variability can be simpler if it deals with the performance variables only. On the other hand, modeling Fitts' law, one should take into account not only the human effector (...) system but features of the experimental apparatus as well. These differences have not been sufficiently reflected in Plamondon & Alimi's target article. (shrink)

We estimate that 208,000 deep brain stimulation (DBS) devices have been implanted to address neurological and neuropsychiatric disorders worldwide. DBS Think Tank presenters pooled data and determined that DBS expanded in its scope and has been applied to multiple brain disorders in an effort to modulate neural circuitry. The DBS Think Tank was founded in 2012 providing a space where clinicians, engineers, researchers from industry and academia discuss current and emerging DBS technologies and logistical and ethical issues facing the field. (...) The emphasis is on cutting edge research and collaboration aimed to advance the DBS field. The Eighth Annual DBS Think Tank was held virtually on September 1 and 2, 2020 (Zoom Video Communications) due to restrictions related to the COVID-19 pandemic. The meeting focused on advances in: (1) optogenetics as a tool for comprehending neurobiology of diseases and on optogenetically-inspired DBS, (2) cutting edge of emerging DBS technologies, (3) ethical issues affecting DBS research and access to care, (4) neuromodulatory approaches for depression, (5) advancing novel hardware, software and imaging methodologies, (6) use of neurophysiological signals in adaptive neurostimulation, and (7) use of more advanced technologies to improve DBS clinical outcomes. There were 178 attendees who participated in a DBS Think Tank survey, which revealed the expansion of DBS into several indications such as obesity, post-traumatic stress disorder, addiction and Alzheimer’s disease. This proceedings summarizes the advances discussed at the Eighth Annual DBS Think Tank. (shrink)

Concerns have been expressed about adult behaviour at children’s sporting events in New Zealand. As a consequence, covert observation was identified as the optimal research method to be used in studies designed to record the nature and prevalence of adult sideline behaviour at children’s team sporting events. This paper explores whether the concerns raised by the ethics committee about the use of this controversial method, particularly in relation to the lack of informed consent, the use of deception, and researcher safety, (...) were effectively managed. This is achieved by reflecting on the conduct and findings of the research and by drawing on the perspectives of research assistants who carried out the covert observation. The authors argue that in the context of these studies, the ends have justified the means and with careful attention to the design of the study the complex ethical tensions arising from the use of this method can be managed.

Liberal neutrality requires that, given the diversity of conceptions of the good life held by people, the state should be in some sense neutral between these conceptions. Just what that sense is has been a matter of debate but it seems generally accepted that neutrality is a property of the justifications for government action and not of the consequences of such action. In other words, the state must be neutral by avoiding invoking any conception of the good in its justification (...) for laws and policies and by avoiding having any laws and policies that can be justified only by reference to some conception of the good. It need not, so it seems generally accepted, ensure that the consequences of its laws and policies do not favor some conceptions of the good over others. Against this commonly held view, in this chapter I argue that justificatory neutrality is inadequate as a full picture of what liberal neutrality means and that some conception of consequential neutrality is more plausible.

In Beyond Neutrality, George Sher criticises the idea that state neutrality between competing conceptions of the good helps protect society from oppression. While he is correct that some governments are non-neutral without being oppressive, I argue that those governments may be neutral at the core of their foundations. The possibility of non-neutrality leading to oppression is further explored; some conceptions of the good would favour oppression while others would not. While it is possible that a non-neutral state may avoid oppression, (...) it is argued that the risks are so great that it is better to bet on government being neutral, thereby minimizing the possibility of oppression.

In the reported, experiment participants hit a ball to aim at the vertex of a Müller–Lyer configuration. This configuration either remained stable, changed its shaft length or the orientation of the tails during movement execution. A significant illusion bias was observed in all perturbation conditions, but not in the stationary condition. The illusion bias emerged for perturbations shortly after movement onset and for perturbations during execution, the latter of which allowed only a minimum of time for making adjustments . These (...) findings indicate that allocentric information is exploited for online control when people make rapid adjustments in response to a sudden change in the environment and not when people guide their limb movements to interact with a stable environment.

A major argument for vegetarianism is that eating animals causes unjustified suffering. While this argument has been articulated by several people, it has received surprisingly little attention. Here I restate it in a way that I believe is most convincing, considering and rejecting the two main justifications for causing suffering in order to eat animals. I compare it to some other prominent arguments for vegetarianism, and discuss a major objection to the argument which focuses on whether the animals would not (...) exist if not bred to be eaten.

Passivity experiences in schizophrenia are thought to be due to a failure in a neurocognitive action self-monitoring system . Drawing on the assumption that inner speech is a form of action, a recent model of auditory verbal hallucinations has proposed that AVHs can be explained by a failure in the NASS. In this article, we offer an alternative application of the NASS to AVHs, with separate mechanisms creating the emotion of self-as-agent and other-as-agent. We defend the assumption that inner speech (...) can be considered as a form of action, and show how a number of previous criticisms of applying the NASS to AVHs can be refuted. This is achieved in part through taking a Vygotskian developmental perspective on inner speech. It is suggested that more research into the nature and development of inner speech is needed to further our understanding of AVHs. (shrink)

This article argues that deciding when to die is a matter of individuality.

This essay addresses the role of trust in political philosophy. In particular, it examines the idea that trust is necessary for a particular type of government action — paternalistic action — to be justified. Liberal theory and liberal democratic practice are characterized by a large degree of anti-paternalism, understanding paternalism to be the restriction of individual liberty for a person’s good, instead of to protect or benefit others. It would be a mistake to think that liberal democracies have no paternalism; (...) seatbelt, motorcycle helmet, and drug prohibition laws, for example, are probably at least partly motivated by paternalistic reasons. But it is easy to imagine more pervasive paternalism. Society could, and does in some cultures, restrict people’s choices of occupation, marriage partners, and where to live, with the rationale that these restrictions are for people’s good. Many people believe that the liberal position is the correct one, that more pervasive paternalism would be unjustified, but what is the philosophical justification for anti-paternalism? (shrink)

Brains are information processing systems whose operational principles ultimately cannot be understood without resource to information theory. We suggest that understanding how external signals are represented in the brain is a necessary step towards employing further engineering tools to understand the information processing performed by brain circuits during behaviour.

The phenomenology of auditory verbal hallucinations occurring in hypnagogic and hypnopompic states has received little attention. In a sample of healthy participants, 108 participants reported H&H AVHs and answered subsequent questions on their phenomenology. AVHs in the H&H state were found to be more likely to only feature the occasional clear word than to be clear, to be more likely to be one-off voices than to be recurrent voices, to be more likely to be voices of people known to the (...) individual than unknown persons, to be more likely to talk directly to the person rather than not, and to only rarely give commands, ask questions, or to result in an interactive conversation. Their phenomenology was similar to normative AVHs in wakefulness in that the voice-hearer was usually the target of the voice, and the voice was more likely to be of a recognized person. However, H&H AVHs differed from AVHs in wakefulness in that commands and questions were rare, and there was typically no dialogical engagement with the voice. We conclude by proposing that two distinct types of H&H AVHs may exist, based on an analysis of the phenomenology of the experience, and suggest avenues for future research. (shrink)

What makes individual freedom valuable? People have always believed in freedom, have sought it, and have sometimes fought and died for it. The belief that it is something to be valued is widespread. But does this belief have a rational foundation? This book examines answers to these questions that are based on the welfare of the person whose freedom is at stake. There are various conceptions of a worthwhile life, a life that is valuable for the person whose life it (...) is. These conceptions will be examined to see whether they are plausible and what their connection, if any, is to freedom. Are they compelling foundations for freedom? Does freedom make a person’s life better or would his/her welfare be advanced by restricting freedom? (shrink)

When, if ever, is paternalism justified? I defend the principle that paternalism is justified only if it is neutral, that is, the motivation for it is compatible with all conceptions of the good life. Three other principles of paternalism are examined. The balancing view says that we must balance the values of liberty and well-being against each other and that paternalism is justified only if well-being outweighs liberty. The consent principle says that paternalism is justified only if consented to. The (...) voluntariness principle says that intervention is justified only when the conduct in question is substantially nonvoluntary. These three views are either implausible, plausible only if they are supplemented with the neutrality principle, or plausible only because they already presuppose that principle. (shrink)

This paper defends Kant against a neo‐Hegelian line of criticism, recently advanced by John McDowell, Robert Pippin, and Sebastian Rödl, targeting Kant's alleged claim that forms of sensibility other than space and time are possible. If correct, the criticism identifies a deep problem in Kant's position and points toward Hegel's position and method as its natural solution. I show that Kant has the philosophical resources to respond effectively to the criticism, notably including the set of claims about the limits of (...) meaningful thought that P. F. Strawson calls Kant's “principle of significance.” By Kant's lights, first, the concept “non‐spatio‐temporal form of sensibility” is meaningless, so he cannot meaningfully grant that such a form is possible; and second, there is no need to prove (e.g., from reflection on pure intellect) that non‐spatio‐temporal forms of sensibility are impossible, because insofar as the concept “knowing” means anything, that meaning is provided by our own always‐already‐spatio‐temporal case. An upshot of the argument is that Kant's two “stems” of knowledge or cognition, sensibility and understanding, are merely aspects of a single epistemic capacity rather than each a separate capacity in its own right. Many today are unwilling to take Kant's claims about the limits of meaningful thought at face value, notwithstanding their ubiquity and explicitness. This paper is therefore an indirect argument on behalf of that dimension of Kant's position: We have something significant to lose in not taking it seriously. (shrink)

This book takes Hollywood's disaster movies and their codified versions of natural disaster, post-apocalyptic survival, and extra-terrestrial threat as the starting point for an analytical trajectory toward new understandings of how cinema shapes and informs our conceptions of disaster and catastrophe. This book examines a range of films from distinct regional and industrial contexts: Hollywood, indie movies, different kinds of documentaries, and auteurist-realist cinema. Moving across and beyond critical and industrial categories that inform thinking about cinema, it contends that different (...) approaches to film style can push us to imagine disaster in distinct ways, with distinct ethical connotations.

Metaphysical readings of Kant’s theoretical philosophy in the Critical period are ascendant. But their possibility assumes the possibility of existence- and real-possibility-judgments about things in themselves. I argue that Kant denies the latter possibility, so metaphysical readings have dubious prospects. First, I show that Kant takes existence- and real-possibility-judgments, as necessarily synthetic, to require a relation to sensible intuition. Second, I show that the most promising metaphysical readings can ultimately neither satisfy nor explain away that requirement for existence- and real-possibility-judgments (...) about things in themselves. I conclude with pessimistic reflections on the prospects for the metaphysical interpretive project. (shrink)

The proposal that there is an illusion of conscious will has been supported by findings that priming of stimulus location in a task requiring judgements of action-authorship can enhance participants’ experience of agency. We attempted to replicate findings from the ‘Wheel of Fortune’ task [Aarts, H., Custers, R., & Wegner, D. M. . On the inference of personal authorship: enhancing experienced agency by priming effect information. Consciousness and Cognition, 14, 439–458]. We also examined participants’ performance on this task in relation (...) to self-reported passivity experiences and hallucination-proneness. We found a significant effect of priming, with primes being found to increase the experience of agency. An interaction between gender and priming was also found, with priming enhancing feelings of agency in women but not in men. There were no significant correlations between levels of self-reported passivity experiences or hallucination-proneness and participants’ susceptibility to the priming effect on ratings of agency. Implications of these findings are discussed with regard to a prominent model of passivity experiences. (shrink)

The voices and visions experienced by Emanuel Swedenborg remain a topic of much debate. The present article offers a reconsideration of these experiences in relation to changes in psychiatric practice. First, the phenomenology of Swedenborg's experiences is reviewed through an examination of his writings. The varying conceptualizations of these experiences by Swedenborg and his contemporaries, and by psychiatrists of later generations, are examined. We show how attempts by 19th- and 20th-century psychiatrists to explain Swedenborg's condition as the result of either (...) schizophrenia or epilepsy are unable to account for his experiences. We then demonstrate that the re-emergence of the 19th-century concept of `hallucinations in the sane' offers an alternative way to understand Swedenborg's experiences outside typical discourses of mental illness. Finally we argue that Swedenborg's experiences should be understood as exemplifying phenomena which we term `hallucinations without mental disorder', and investigate how conceiving of Swedenborg in this way can inform future research into the experience and clinical significance of hallucinations.

This paper discusses the semiotic dimension of patent interpretation. Patent documents are at the same time disclosure of information and a granting of rights. The claim section expresses the granted rights. In this paper, we view the claims as signs that express the granted rights. The semantics to interpret the signs is given by the all-elements rule, as pragmatics. The description and drawings sections of the patent document provide metapragmatics in the form of lexicon and syntax to help the understanding (...) the claims as signs that express the granted rights. This semiotic approach for patent interpretation has important practical consequences to the correct structuring of a patent document. We highlight this contribution through an instance of a patent application in which a claim includes examples of use. Examples are not allowed in the claim text, as examples do not describe the invention, but consist of metapragmatics to better understand the invention. In this way, examples consist of metapragmatics and belong to the description section of the patent, which has the goal to facilitate the understanding of claims. In the patent application used to highlight our semiotics approach for patent interpretation, the examples initially presented in the claims were rephrased in the final granted patent, significantly reducing the scope of the claim.

The aim of this book is to explore some of the relations between morality and politics. Areas in which these are explored include the role of ideals in foreign policy , committing evil for the sake of a greater good in wartime, and lying and deception in political affairs. Illustrative examples are used throughout and include the Iraq war and its political fallout , Allied and Axis actions during the Second World War, decisions made by former Australian Prime Minister John (...) Howard and thought-experiments such as whether to lie about the Jewish family hiding in the basement when the Nazis come knocking at the door.Chapters 1 and 2, making up the first half of the book, are the highlight of it. In them, Coady confronts the realist critique of morality in foreign …. (shrink)

Business Ethics: A European Review, EarlyView.

The standard dogmatism ignores the fact that neural coding is extremely flexible, and the degree of “coarseness” versus “locality” of representation in real brains can be different under different task conditions. The real question that should be asked is: What is the operating point of neural coding under natural behavioural conditions? Several sources of evidence suggest that under natural conditions some degree of distribution of coding pervades the nervous system.

The sense of touch informs us of the physical properties of our surroundings and is a critical aspect of communication. Before touches are perceived, mechanical signals are transmitted quickly and reliably from the skin's surface to mechano‐electrical transduction channels embedded within specialized sensory neurons. We are just beginning to understand how soft tissues participate in force transmission and how they are deformed. Here, we review empirical and theoretical studies of single molecules and molecular ensembles thought to be involved in mechanotransmission (...) and apply the concepts emerging from this work to the sense of touch. We focus on the nematode Caenorhabditis elegans as a well‐studied model for touch sensation in which mechanics can be studied on the molecular, cellular, and systems level. Finally, we conclude that force transmission is an emergent property of macromolecular cellular structures that mutually stabilize one another. (shrink)

Memories and Monsters explores the nature of the monstrous or uncanny, and the way psychological trauma relates to memory and narration. This interdisciplinary book works on the borderland between psychology and philosophy, drawing from scholars in both fields who have helped mould the bourgeoning field of relational psychoanalysis and phenomenological and existential psychology. The editors have sought out contributions to this field that speak to the pressing question: how are we to attend to and contend with our monsters? The authors (...) in this volume examine the ways in which we might best relate to our monsters, and how the legacies of ancient traumas and anxieties continue to affect our current stories, memories and everyday practices. Covering such manifestations of the monstrous as racism, crimes against humanity, trauma as portrayed in music and art, and the Holocaust, this book explores the impact the uncanny has on our individual and collective psyches. By focusing on a very specific theme, and one that excites the imagination, Memories and Monsters stokes the flames of an important current movement in relational psychoanalysis. It will appeal to psychoanalysts and psychoanalytic psychotherapists, as well as professionals in psychology and graduate school students and tutors in the fields of both psychology and philosophy.

Calls are increasing for American health care to be organized as a learning health care system, defined by the Institute of Medicine as a health care system “in which knowledge generation is so embedded into the core of the practice of medicine that it is a natural outgrowth and product of the healthcare delivery process and leads to continual improvement in care.” We applaud this conception, and in this paper, we put forward a new ethics framework for it. No such (...) framework has previously been articulated. The goals of our framework are twofold: to support the transformation to a learning health care system and to help ensure that learning activities carried out within such a system are conducted in an ethically acceptable fashion.

Participants in clinical research sometimes view participation as therapy or exaggerate potential benefits, especially in phase I or phase II trials. We conducted this study to discover what methods might improve cancer patients’ understanding of early-phase clinical trials. We randomly assigned 130 cancer patients from three U.S. medical centers who were considering enrollment in a phase I or phase II cancer trial to receive either a multimedia intervention or a National Cancer Institute pamphlet explaining the trial and its purpose. Intervention (...) participants were 32 times more likely to believe that the trial’s purpose was to examine safety and 60 % less likely to believe they would experience long-term benefit or cure. There was no difference in enrollment decision. However, while patients’ understanding of the trial’s purpose improved and expectations of long-term benefit diminished, half the respondents still believed they would experience long-term benefit or cure from participation. Therefore, we conclude that multimedia interventions such as this one may help oncologists to explain the risks and benefits of early-phase cancer trials in a way that patients can more easily understand, helping them to make more informed decisions about participation. But further research into other factors that influence patients’ beliefs about the outcome of enrollment is needed, both to modify the interventions and to determine how malleable patient beliefs are.

The cholinergic system is a good candidate for the role of determining the relative weight given in cortical information processing to new sensory information versus prior knowledge. We discuss the physiological data supporting this, and suggest that this Bayesian perspective can easily be reconciled with the dynamical framework proposed by Behrendt & Young.

Recent legislation, such as the Patient Self-Determination Act, establishes advance directives as an acceptable procedural means of incorporating patients’ preferences for life-sustaining treatments into their medical care. Advance directives can enhance medical decision making since they provide patients with an opportunity to communicate their preferences before suffering from an acute illness that may preclude their ability to do so.Although patients expect discussions about life-sustaining therapies to be initiated by their physicians, very little is known about what prompts physicians to discuss (...) advance directives with their patients. As in other areas of clinical decision making, there is evidence that patients’ sociodemographic factors influence whether discussions about advance directives occur between patients and their physicians. In one study of persons with the acquired immunodeficiency syndrome, those who had not had discussions about advance directives with their physicians tended to be non-white, have no prior hospitalization, and were more likely to have been cared for in a health maintenance organization than in a teaching hospital.
